Type 8400 - Screw-in temperature threshold detector/transmitter with display

Type Description

This intelligent threshold detector/transmitter with an extra large display is specifically designed to monitor limit values or an ON/OFF or continuous control loop. Two variants are available: the Type 8400 Compact and Type 8400 for wall mounting. The wall-mounted variant must be inserted into a holder previously mounted on a wall, and it must be associated with a remote temperature sensor. The switching points can be programmed with keys directly in the display or optionally with a 4...20 mA standard signal input from an external PLC. As an option, the process value can additionally be transmitted to the PLC (with a 4...20 mA signal). The connection of the Type 8400 to the process in the piping is made using standard T-fittings with standard connections (G ½).
